Wet bulb globe temperature, or WBGT, is a heat stress metric designed to reflect environmental heat load more realistically than air temperature alone. It is commonly used when people must make decisions about exertion, heat exposure, scheduling, rest breaks, and event operations.
Air temperature tells you how hot the air is. WBGT is broader. It is designed to reflect several conditions that shape how hot it actually feels to a person who is outside, exposed to sun, moving, working, or exercising. In practice, that means WBGT is often more useful than standard temperature for heat stress decisions.
Depending on the method used, WBGT incorporates environmental effects such as humidity, solar load, wind, and the temperature of the surrounding environment. Those factors matter because the body’s ability to cool itself depends heavily on evaporation, radiant heat gain, and airflow.
Organizations use WBGT when a simple “it’s hot today” answer is not enough. Coaches, athletic trainers, construction crews, utility operators, event planners, school systems, military programs, and safety leaders often need a better picture of heat stress conditions across time and location. That is where a WBGT forecast or live WBGT app becomes useful.
Klimo WBGT is a forecast and decision-support app built around wet bulb globe temperature and related heat stress conditions. It is intended to help users understand current conditions, expected changes, and practical planning windows. It does not replace your own policies, medical judgment, or operational protocols.
